Abstract
1513058 Alignment of props HERMANN HEMSCHEIDT MASCHINENFABRIK 16 Dec 1975 [21 Dec 1974] 51476/75 Heading E1P A prop-and-shoe assembly comprises a hydraulic prop, having a bearing member 24 at one end which is supported on a pivot 28 on the shoe 16 and having a tubular portion 22 which slides over the bearing member 24, a chamber 30 within the prop to which hydraulic fluid may be admitted via a passage 32, an abutment 34 on the lower end of the prop, and a stop 36 on the shoe against which the abutment may be raised by supplying hydraulic fluid to the chamber 30 in order to align the prop relative to the shoe. The bearing 24 and pivot 28 are in the form of a ball and socket joint. A bellows type sock 38 protects the joint from dirt.
